Where to measure on the flywheel to check what generation 1G i have?

Around $450ish for a button from either extreme or exedy, ive used both and seem to hold up well. Thats for a 225mm clutch. Not sure on a cushion button prices though id say they are similar

yeah my exedy cushioned button was 550 or so, from supercheap, so not the cheapest price you could get.

for the 236mm one it was like $100 more expensive i think. Just go onto the exedy website, get the part number and call around..

Thanks guys. I guess thats the best value for money you're going to get
